Check out this bright handlebar addition: The Brilliant 5 LED Headlight keeps you visible at night, helps you see the road ahead, and scares away the boogie man on the bike path. Click for Instruction Manual

Featuring LuminMax Technology, this light produces 500 candlepower, includes a steady and flash mode and offers great side visibility, too

Water-resistant design is great for commuting in bad weather

Tool-free installation and removal lets you take it off the bike when you get where you're going

A great deal for the visibility alone!! This little light is inexpensive, an although not robust in constructuion, has more durability than flashing lights costing much more. This light could be a life saver for dawn or disk rides, or coming in and out of shadows. Drivers pulling out on the right side will see this light or they are leagally blind! Runs for weeks on 3 AAA alkaline batteries. I keep it on during the whole ride. Easy to mount on handlebar.

This light is great, except for one fatal flaw: the battery life is pretty terrible. It is no longer brighter than its competitors after about 2 weeks of daily use (only about 20min per day on flash mode), and the batteries need to be replaced after about a single month. Comparable planet bike lights, although they might not be quite as bright, will last for 6 months or so with comparable use, and even the $1 lights I ordered direct from [*] had longer battery life.Other than the battery life, it is nice and small, really bright(not quite enough for trail biking or anything), and the mount seems pretty secure.

I commute by bike in New York City, where pretty much everywhere is well lit all the time, so my bike lights are mostly for lighting myself. In the past, I've used Planet Bike lights - specifically the Blaze Half-Watt LED. I've liked these lights except for one thing - I'm not all that great at not loosing them, and they get pricey at about $30 each, [$] for a set. I probably loose one set a year, so it is easily the most expensive part of maintaining my bike. This light is a fair bit cheaper, and after doing the "shine it against a wall" and "look at the reflection in a window" test, it is brighter than the Planet Bike 1/2 Watt as well. Furthermore, it is small and light.I haven't yet used it for more than a day, but it seems pretty good. My only qualm is that the mounting system seems sort of insecure; you don't need any tools to mount it, which is nice, but it seems like it might be prone to turning down toward the ground as I can twist it by hand. I haven't had quite enough experience with this light to confirm that it has this problem, but I've experienced this with lights before, and it usually just means that you need to adjust the light every now and then, so it's not that bad if it is.

price is nice. Light isn't uselessly dim. Yet it is not even water _resistant_, let alone waterproof. I live in the Pacific Northwest, in the Puget Sound region. I believe it lasted maybe a month. One day, would simply not turn on. Replaced batteries, still nothing. No crashes in that time, so my only guess would be that it managed to short out. Maybe I'm wrong on the why, _but_, if it's not water, then it's even more prone to breakage for even less explicable reasons. If you'll be riding in a very dry area, maybe this could work for you, but wouldn't recommend risking it otherwise.

REALLY, if you'll be using it regularly, I know it seems exorbitant, but NBR sells some _much_ brighter, _much_ more durable lights. Bite the bullet - you'll thank yourself as soon as you're going downhill @>30mph! At least 300 lumens.

If you're looking for a light that won't break your budget this is it. The light is bright enough for you to actually see the road ahead. Very easy to install and remove from the handle bars. Excellent value

Great light for the price. Really quick on/off, so you don't have to keep it permanently mounted on handlebars. Only downside is it's plastic, so just don't drop it, but it only cost [$] and keeps me quite visible. I think it was a great buy.

Bought because other light at LBS was not bright enough. Bought this and $10 one during FREE shipping and was a little disappointed. It is now on second bike that is riden only during day and use the flash mode.
